1 Claim. 1

My invention relates to film splicing devices. While intended for usemore particularly for splicing motion picture film. it is to beunderstood that this device may be used for splicing other types offilm.

An object of this invention in general is to provide an efficient andconvenient device and method of making cuts and splices in film with aminimum amount of effort and inaccuracy and Without the requirement ofany great degree of skill, so that the splicing can be satisfactorilyperformed by persons who have no special training for this kind of work.A special object of the invention is to provide a device and method bywhich the cut ends of film may be properly joined together withoutrequiring the delicate operation of scraping the emulsion from the cutends.

The novel features, which I believe to be characteristic of thisinvention, are set forth with particularity in the appended claim. Theinvention itself, however, both as to organization and operation,together with additional objects and advantages thereof, will be bestunderstood from the following description of a specific embodiment whenread in connection with the accompanying drawings in which- Fig. 1 is atop view of the device.

Referring to the construction shown in the drawings for the purpose ofillustrating the principles involved in this invention, the numeral 20as best shown in Fig. 2 designates a casing which constitutes a base forthe device and which contains light bulbs 2|. A frame member 22 issecured to the top of the casing 20 and is provided with track-ways 23and 2t shown in Fig. 19 in which the flanged bottom of two film carriers.25 and 26 shown in Fig. 1 may be slid toward and away from each other,so that in one extreme position they will be separated from each otherby a space equal to the length of one film picture, and in the otherextreme position they will butt against each other. These carriers areprovided with openings 21 and 28, respectively shown in Figs. 5 and 8,each opening corresponding in shape with that of one picture section.

In order that the two film carriers when sep-.

arated may be spaced from each other exactly the length of one picturesection, the ends of the frame 22 have upstanding flanges 29 and 30'through which adjustable stops 3| and 32 extend. In order to slide thefilm carriers backwardly and forwardly, a double crank member 33 iscentrally pivoted at 34 to the frame member 22. One crank arm of themember 33 shown in Fig. 2 is connected by a rod 35 with the carrier 25while the other crank arm is connected by a rod 36 with the carrier 26.The opposed ends of the carriers 25 and 26 are provided, respectively,with die members 31 and 3B integral therewith slightly depressed belowthe upper surface of the carriers. Back of the dies 31 and 38, thecarriers are provided with upstanding pins 39 for engaging in the feedperforations at the sides of the film, as shown in Fig. 4. These pinsserve, after a picture section has been cut out, for feeding the two outends of the filmv into butted position.

Clamping plates 40 and 4| are hinged at 42 and 43, respectively, to theback side of the fram member 22. These plates at their front areprovided with finger pieces 44 and 45, respectively. These finger piecesat their front carry spring members 46 as shown in Figs. 4 and 19, thelower ends of which have struck out projections 41 adapted to engagewith outstanding flanges 48 positioned at the front of the filmcarriers. The clamping plates 40 and M serve to hold the film in placefor the cut at the time when the film carriers 25 and 26 are separatedfrom each other. The clamping plates 40 and 4| are provided withopenings 21 and 28' which are in register with the openings 2'! and 28so that the film is illuminated by light which comes up through theseopenings. from tho, bulbs 2!. {killer the. c ut in. the film has beenmade, in the manner later." to; be described, these plates insure thatthe cut ends of the film will be fed toward each other in order that abutt splice may be made, in a manner now to be described.

As best shown in Figs. 3 and 4, an an gpla r member 49 is pivoted at 5!)to projections 5| extending up from the frame. The.- member Q9 carriesan angle member 52 having a forwardly extending flange 53. Ahand-operated lever 54 has its rear endpositioned under the flange 53.[downwardly extending rod 55 is secured-tothe lever 54 and passesthrough a hole in the member 48 with'a'block 55 secured-to the lower endof the rod. This block is adapted toslide. up and down on posts 51'whoselower ends are secured to a punch 58; which extends forwardly fromthemeinber t9. The upper endsof these posts are secured to theupper-portion; of the member 4 8. lever 54 is normallyheld in upwardposi'tipn by a coiledspring- 59' surr ounding'therod 55 and interposedbetween this lever and the forward extension of the member- 45.

Since this film has no coating of emulsion, noscraping is necessary and only a short time of applied pressure by thepressure foot is sufficient to make a strong splice for the butted endsof the two pieces of The operation and advantages of my invention willbe obvious from the foregoing description and have, to a large extent,been indicated.

Fig. 14 shows that the filmstrip 63 has been applied to make theisplice. Fig. 15 is a fragmentaryenlarged View of the film, after it has been spliced.

Referring more in detail to the operation of the device, it sh oulci benoted that when the die members 3 and 38 are in separated condition andthe punch 58 is depgessed to out the picture film, the splicing film 63.has not yet been drawn forwardly through the. slot 66; Therefore thepresser.- member 651 will pass downwardly in the slot $43.01 the. punch.58' without contacting the splicing film. The spring. 58 is then allowedto lift the punch 58 as well as thepresser When the adhesive has beenapplied to the butted ends of; the picture film, the splicing film isdrawn forwardly above the adhesive. Now when the lever: 54: is, againdepressed, the presser 65' not only cuts the splicing piece-out of thefilm 53 but also, presses this piece firmly upon the cement. During thistime, they punch Elsimply rests over the dies}?! and and. on the uppersurface of the picture film.

Iiclaim:
